United States Patent 3,292,638 SMOKING PIPE Claude Lorquet, 370 SunsetDrive, Hamburg, N.Y. 10115 Filed June 8, 1964, Ser. No. 373,334 3Claims. (Cl. 131183) This invention relates to smoking pipes andparticularly to a supporting and ejecting means for the tobacco in thepipe bowl.

In the prior art various ejecting devices for the used tobacco or dottlein a pipe bowl have been proposed. The present invention provides animproved device of this general character which, in addition to itsejecting function, forms a leak-proof moisture receiving well in thebottom of the pipe bowl.

Furthermore, the device of the present invention provides a support forthe tobacco which retains the same above the level of the bore whichdischarges into the bowl from the stern of the pipe. Thus the fullcharge of tobacco is maintained in a clean, dry condition until it hasbeen fully consumed.

In addition to the foregoing the present invention provides an ejectorseal construction which may readily be applied to smoking pipes ofconventional construction and which is so arranged that the seal elementthereof may be readily replaced if such replacement becomes necessary.Other objects and advantages of the device of the present invention willbecome apparent to those skilled in the present art from a perusal ofthe following specification and the accompanying drawing.

While a single specific embodiment of the principles of the presentinvention is illustrated in the accompanying drawing and described indetail in the following specification, it is to be understood that suchembodiment is by way of example only and that various mechanicalmodifications may be made without departing from the spirit of theinvention, the scope of which is limited only as defined in the appendedclaims.

In the drawing:

FIG. 1 is a partial longitudinal cross sectional and elevational viewthrough a smoking .pipe provided with one form of the tobacco supportingand ejecting device of the present invention; and

FIG. 2 is a top plan view of the ejecting device portion of thestructure of FIG. 1.

In the drawing like characters of reference denote like parts and thenumeral designates generally a smoking pipe having a bowl 11 and a stem12. In FIG, 1 the tobacco receiving chamber of the bowl is designated 13and the communicating bore in the stem is designated 14.

In applying the device of the present invention to the foregoingconventional smoking pipe the bottom of the pipe bowl is bored toslidably receive a rod 15 and the bore is counterbored and internallythreaded at its lower end as indicated at 16 in FIG. 1. An O-ring 17 isplaced in the counterbore about the rod 15 and an annular screw 18,likewise disposed about rod 15, is tightened against the O-ring toflatten the same as indicated in FIG. 1. The proportions of the O-ringare such that pressure of screw 18 thereagainst urges the internalperiphery of the O-ring against rod 15 to permit sliding movement and toseal the same so that moisture in the bowl will not leak downwardly pastthe rod 15.

In FIG. 1 the supporting and ejecting device is shown in its normaloperating position and a disc 20 is fixed to ice the upper end of rod15, as by riveting the upper end of the rod over the disc 20. It will benoted that disc 20 is of such diameter that, in its lowermost operatingposition, it engages and seats against the interior wall of bowl 11above the level at which bore 14 enters the chamber 13.

Disc 20 is perforated as shown at 21 in FIG. 2 to permit free passage ofair and smoke. A spacing sleeve or ferrule 22 is disposed about rod 15between disc 20 and the bottom of the chamber 13. A manipulating button24- comprises a disc which is threaded to the lower end of rod 15. Whenthe contents of chamber 13 are to be discharged the pipe is merelyturned over and button 24 is depressed to move disc 20 toward the top ofbowl 11. The natural taper of the wall of chamber 13 of the bowl 11allows the accumulation of a desired cake formation on the chamber wall.

The frictional fit of rod 15 in the seal formed by O- ring 17 ispreferably sufficiently tight to avoid inadvertent movement of the rod15 so that the contents of the pipe will not be discharged accidentally.This relatively close fit also permits the button 24 to be used as arest for the pipe to support the same in upright position on a table orthe like.

I claim:

1. In a smoking pipe comprising a bowl having a tobacco receivingchamber having upwardly and outwardly tapering wall portions and a stemhaving a passage communicating with the lower portion of said chamber,said bowl having a vertical central bore through its bottom and a rodslidable vertically therein, a perforated disc fixed to the upper end ofsaid rod within said chamber above said passage, and an operating buttonfixed to the lower end of said rod, said vertical bore having aninternally threaded counterbore in its lower end and having a downwardlyfacing annular shoulder, a compressible annular seal in said counterboreand an annular screw disposed about said rod and threaded into saidcounterbore to compress said seal against the shoulder and urge the sameradially inwardly against said rod sufiiciently to seal the same againstleakage and to permit said rod to he slid with respect to the seal andscrew to move said disc from a lower tobacco supporting to an upperdisdischarging position.

2. In a smoking pipe comprising a bowl having a tobacco receivingchamber having upwardly and outwardly tapering wall portions and a stemhaving a passage communicating with the lower portion of said chamber,said bowl having a vertical central bore through its bottom and a rodslidable vertically therein, a perforated disc fixed to the upper end ofsaid rod within said chamber above said passage, and an operating buttonfixed to the lower end of said rod, said vertical bore having aninternally threaded counterbore in its lower end and having a downwardlyfacing annular shoulder, a compressible annular seal in said counterboreand an annular screw disposed about said rod and threaded into saidcounterbore to compress said seal against the shoulder and urge the sameradially inwardly against said rod sufliciently to seal the same againstleakage and to permit said rod to he slid with respect to the seal andscrew to move said disc from a lower tobacco supporting to an upperdischarging position, said disc being proportioned to engage the innerwall of said bowl above said passage when in its lower position andmovable upwardly by pressure against said operating button to eject thecontents of said bowl.

3. In a smoking pipe comprising a bowl having a tobacco receivingchamber having upwardly and outwardly tapering wall portions and a stemhaving a passage communicating with the lower portion of said chamber,

said bowl having a vertical central bore through its bot tom and a rodslidable vertically therein, a perforated disc fixed to the upper end ofsaid rod within said chamber above said passage, and an operating buttonfixed to the lower end of said rod, said vertical bore having aninternally threaded counterbore in its lower end and having'a downwardlyfacing annular shoulder, a compressible annular seal in said counterboreand an annular screw disposed about said rod and threaded into saidcounterbore to compress said seal against the shoulder and urge the sameradially inwardly against said rod sufficiently to seal the same againstleakage and to permit said rod to be slid with respect to the seal andscrew to move said disc from a lower tobacco supporting to an upperdischarging position, a spacing sleeve disposed about said rod withinsaid bowl and beneath said perforated disc to establish a lower limitposition of said disc, said lower limit position being above said stempassage.
